Hydroelectric
power has already been in use for the last few decades all around the
world. Essentially it is the use of water to operate turbines to produce
electricity. Just as with wind energy, the idea is simply a modification
of the old idea of using water wheels. One way to extract hydro energy
would be: piping water so that it falls through tubes down the sides of
mountains, would produce electricity. Alternatively, dams can be built so
that large lakes form and again, by letting water from the lake pass over
turbines, you can produce electricity. But just as with wind energy,
hydroelectricity can use up lots of land. Many power plants in Africa to
produce hydroelectricity have been the cause for floods of many millions
of acres of land and made millions of inhabitants homeless. Since this has
turned into quite a threatening problem, people are rather turning to
micro-hydro projects: small-scale hydroelectricity schemes for individual
villages or projects.
